Single Cartridge Activated Carbon Filter
Single Cartridge Activated Carbon Filter is a cylindrical granular activated carbon filter element used to reduce odors, volatile organic compounds and certain gas-phase contaminants in industrial and commercial ventilation systems.
Cartridges with an outside diameter of Ø145 mm are available in 400, 450 and 600 mm length options. Standard- and high-capacity cartridge designs can be filled with different activated carbon or chemically impregnated media types according to the target contaminant.

Granular Activated Carbon
What Is a Single Cartridge Activated Carbon Filter?
A single cartridge activated carbon filter is a replaceable gas-phase filter element designed to adsorb gas molecules from the airflow onto the surface of granular activated carbon. The cartridge body retains the activated carbon granules within a controlled bed and allows air to pass through the media.
The cartridges are filled using a vibration-assisted filling method to reduce voids that could cause uncontrolled airflow between the granules. Therefore, the method helps create a more uniform carbon bed and improves utilization of the cartridge volume.
The single-cartridge design can be used as a replacement filter element in existing multi-cartridge housings, specially manufactured gas filtration cells or project-specific modular filtration systems.

Cartridge Selection Criteria
- Chemical type of the target gas or VOC compound
- Contaminant inlet concentration
- Airflow per cartridge
- Required carbon contact time
- Standard- or high-capacity requirement
- Operating temperature and relative humidity
- Virgin or impregnated carbon requirement
- Cartridge length and filling volume
- Mounting socket and gasket dimensions
- Particulate prefiltration level
Maintenance and Cartridge Replacement
The service life of an activated carbon cartridge should not be determined solely by pressure drop. The carbon bed may lose adsorption capacity for the target gas or odor compound before becoming physically clogged.
Replacement time should be determined based on inlet and outlet gas measurements, odor breakthrough, carbon sample analysis, estimated saturation calculations or a planned service interval.
When removing and disposing of used cartridges, the nature of the adsorbed chemicals should be considered. Appropriate personal protective equipment should be used, and the facility’s waste management procedures should be followed.
